Bernie Sanders may be on track for a big win in Nevada, Ed Henry reported today.

Henry said that a new CNN/ORC poll shows Nevada voters are split virtually evenly among Sanders and Hillary Clinton days before Saturday's caucuses, the next contest in the race for the Democratic presidential nomination.

Henry said that Clinton is trying to play the 2016 campaign up as a "national race," bigger than any one contest, and that's why she's campaigning outside Nevada this week.

"Yes, she believes it's a national race, but when you're struggling in some states, you also are more likely to say it's a national race, because you don't want the media to focus on any one contest," Henry said.
